Canon EOS M
Canon EOS M is the first mirrorless interchangeable-lens camera produced by Canon. DPReview noted that the EOS M is effectively a miniature version of the Canon EOS 650D, which was introduced in June 2012, with a simpler physical interface. The letter M in EOS M stands for "mobility" and EOS means "electro-optical system". It was superseded by the Canon EOS M2 in late 2013; the Canon EOS M3 in February 2015; the Canon EOS M10 in October 2015; the Canon EOS M6 in August 2017; and the Canon EOS M50 in March 2018. Design The camera has a 3-inch touchscreen with support for multi-touch gestures such as pinch to zoom, swiping and tapping. The camera uses an 18 megapixel APS-C sensor and a DIGIC 5 processor, similar to the Canon EOS 650D. The camera uses an EF-M lens mount which can accept Canon EF and EF-S lenses with an additional mount adapter. Several EF-M lenses, including a 11–22mm f/4–5.6 IS STM, a 22mm f/2 STM pancake lens, an 18–55mm f/3.5–5.6 IS STM, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Touchscreen
A touchscreen or touch screen is the assembly of both an input ('touch panel') and output ('display') device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is opti ...

Canon EOS R
The Canon EOS R is a 30.3 megapixel full-frame mirrorless interchangeable-lens camera launched by Canon in October 2018. The "R" in EOS R comes from the first letter of "Reimagine optical excellence", Canon's development concept for both the EOS R system as a whole, and also for this EOS R camera which launched the new system. Features The EOS R was Canon's first full-frame mirrorless camera, and introduced the new EOS R system and the RF lens mount. Using an EF-EOS R mount adapter, the EOS R can accept all Canon EF and EF-S lenses. The DIGIC 8 processor is used. Sensor The Canon EOS R uses a full-frame (36×24mm) CMOS sensor, which can produce a still image of up to 6720×4480 pixels. ISO sensitivity can be set to values between 100 and 40,000 by default, but the EOS R can be configured to expand the permitted range down to 50 and up to 51,200 or even 102,400. The sensor is able to achieve a dynamic range of 13.5EV at ISO 50. This dynamic range is considered good, but i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patch (computing)
A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, with such patches usually being called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. The majority of patches are provided by software vendors for operating system and application updates. Patches may be installed either under programmed control or by a human programmer using an editing tool or a debugger. They may be applied to program files on a storage device, or in computer memory. Patches may be permanent (until patched again) or temporary. Patching makes possible the modification of compiled and machine language object programs when the source code is unavailable. This demands a thorough understanding of the inner workings of the object code by the person creating the patch, which is difficult without close study of the sourc ...

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon EOS Flash System
Canon's EOS flash system refers to the photographic flash mechanism used on Canon's film (35mm and APS) or digital EOS single-lens reflex cameras. The line was first introduced in 1987. It has gone through a number of revisions over the years, as new flash exposure metering systems have been introduced. The main light-metering technologies are known as A-TTL, E-TTL, and E-TTL II. The EOS flash system is capable of wireless multiple flash control, whereby a master flash unit IR ( ST-E2) or RF ( ST-E3-RT) transmitter mounted on the camera body can control up to 3 (optical) or 5 (radio) groups of flash units. The Canon EOS 7D is the first Canon body to be able to control Speedlites wirelessly without the use of a Master Speedlite or IR transmitter; four other EOS models, the 60D, 600D, 650D, 70D, and 700D, also have wireless flash capabilities. The 7D is capable of handling three slave groups. The other cameras can handle two slave groups. Metering systems Canon has in ...

Canon EF-S Lens Mount
The Canon EF-S lens mount is a derivative of the EF lens mount created for a subset of Canon digital single-lens reflex cameras with APS-C sized image sensors. It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more clearance, allowing lens elements to be closer to the sensor than in the EF mount. Only Canon cameras released after 2003 with APS-C sized sensors support the EF-S mount. The "S" in EF-S has variously been described by Canon as coming from either "Small image circle" (the lens projects a smaller image circle than normal EF lenses to match the sensor), or "Short back focus" (the smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, reducing the minimum distance between the sensor and the back element of the lens). The combination of a smaller sensor and shorter back focal length distanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon EF Lens Mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on 22 April 2014. History The EF mount replaces its predecessor, the FD mount. The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechanism, only electrical con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lens Mount
A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. Mount types A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in us ...

DIGIC 5
Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix. Currently, DIGIC is implemented as an application-specific integrated circuit (ASIC) designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras. DIGIC in Cameras Original DIGIC The original DIGIC was used on the PowerShot G3 (Sep 2002), Canon S1 IS (Mar 2004), A520 (Mar 2005), and other came ...
